Connect to JBoss 7 using VisualVM - jboss7.x

Question

I have remote JBoss 7.1 server and I would like to connect to this server by using VisualVM or JConsole.
I googled a bit and found several threads/tutorials on how to connect to JBoss 7.1 by using VisualVM or JCoonsole, e.g.:
https://community.jboss.org/thread/171346?start=0&tstart=0
https://issues.jboss.org/browse/WFLY-895
https://community.jboss.org/wiki/UsingJconsoleToConnectToJMXOnAS7
http://blog.akquinet.de/2012/11/01/connecting-visualvm-with-a-remote-jboss-as-7-eap6-jvm-process/
Unfortunately I had no luck in connecting to my JBoss 7.1 over JMX.
Do you have any ideas how to connect to JBoss 7.1 with VisualVM?
EDIT:
I added -Dcom.sun.management.jmxremote.port=1090 -Dcom.sun.management.jmxremote.authenticate=false to standalone.conf.bat, but I got an exception:
Caused by: java.lang.IllegalStateException: The LogManager was not properly inst
alled (you must set the "java.util.logging.manager" system property to "org.jboss.logmanager.LogManager").
So, I added another option to JAVA_OPTS: -Dcom.sun.management.jmxremote.port=1090 -Dcom.sun.management.jmxremote.authenticate=false -Djava.util.logging.manager=org.jboss.logmanager.LogManager
but the exception I receive is this:
Could not load Logmanager "org.jboss.logmanager.LogManager"
java.lang.ClassNotFoundException: org.jboss.logmanager.LogManager

Answer 1

Found a solution. I needed to add the following params to JAVA_OPTS in standalone.conf.bat:
-Dcom.sun.management.jmxremote.port=1090 ^
-Dcom.sun.management.jmxremote.authenticate=false ^
-Dcom.sun.management.jmxremote ^
-Dcom.sun.management.jmxremote.ssl=false ^
-Djava.util.logging.manager=org.jboss.logmanager.LogManager ^
-Xbootclasspath/p:<JBOSS_PATH>/modules/org/jboss/logmanager/main/jboss-logmanager-1.2.2.GA.jar ^
-Xbootclasspath/p:<JBOSS_PATH>/modules/org/jboss/logmanager/log4j/main/jboss-logmanager-log4j-1.0.0.GA.jar ^
-Xbootclasspath/p:<JBOSS_PATH>/modules/org/apache/log4j/main/log4j-1.2.16.jar -Djboss.modules.system.pkgs=org.jboss.logmanager
Note 1: Use \ instead of ^ on Unix.
Note 2: Replace <JBOSS_PATH> with your JBoss 7.x installation path. Mine was c:/java/jboss-as-7.1.1.Final.

You can connect directly to the JBOSS JMX instead of the VM one (no need to modify JAVA_OPTS)
Just ensure you have the following config in standalone.xml (JMX subsystem active)
in standalone mode (listened port 9999):
<subsystem xmlns="urn:jboss:domain:jmx:1.1">
<show-model value="true"/>
<remoting-connector />
</subsystem>
in domain mode (listened port 4447)
<subsystem xmlns="urn:jboss:domain:jmx:1.1">
<show-model value="true"/>
<remoting-connector use-management-endpoint="false"/>
</subsystem>
Then we need a little hack : As JBoss JMX implementation is a bit specific we need to include some jboss lib to the classpath of JVisualVM
Get the file $JBOSS_HOME/bin/jconsole.sh/jconsole.bat and copy / rename it to jvisualvm.sh / jvisualvm.bat in the same directory.
Then replace the executable call to jconsole per jvisualvm using -cp:a "$CLASSPATH"instead of -J-Djava.class.path="$CLASSPATH"
Now just launch visualVM using the script and add a new JMX connection (file menu) using the folowing url service:jmx:remoting-jmx://hostname:port (the credentials are the one of management realm)
NB: think to ssh tunnel if you don't have direct access to JMX port

Answer 3

If you open a command shell and type "netstat -a", do you see something LISTENING on the JMX port 1090? If not, perhaps you have to check JBOSS configuration.

Add the JVM opts to run.conf (run.conf.bat)
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.port=9999 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote"
In Visual VM console open a remote host. And Add JMX Connection and give port number as <9999>
